This repo is currently a work in progress

• The README.md will be fully updated once the repo is in a stable state

TODO

• Need to automate Rust project (xbnet)
  • Configure (looks good)
  • Build
  • Deploy
    • On Ubuntu for testing
    • On Linux for Tegra for TX2
    • On Jetson Orin
• Working on setup_host_device.sh
  • Issues with bridging interfaces
• Need to add setup_end_device.sh
• Need to dockerize service
• Possibly may need to bridge docker xbnet network with local wifi interface as well
• Make a submodule of xbnet, or copy over raw files, depending on future decisions

SERVICES-XBEE_NET

This project contains a Dockerized setup to create and manage an XBee network using the xbnet utility. The network interface is bridged with a host Wi-Fi interface, enabling internet access for connected devices.

Note: This project uses the tap xbnet protocol, which is a layer 2 protocol. This supports full ethernet pipeline. For a simple IP level protocol support, the tun xbnet protocol can be used.

Prerequisites

Ensure Docker and Docker Compose are installed on your machine.

Getting Started

1. Clone the Repository

git clone https://git.spirirobotics.com/Spiri/services-xbee_net
cd services-xbee_net

2. To run the project in PRODUCTION mode, use the following cmd:

• docker-compose -f docker-compose.yml up --build

• Configure the project for user specs, modify the docker-compose.yml file for the following parameters:

  environment:
      - XBEE_INDEX=1
      - XBEE_BAUDRATE=230400
      - XBEE_PORT=/dev/ttyUSB0
      - XBNET_BASE_SUBNET=2.2.2
      - XBNET_INTERFACE_TYPE=router     # ["router" | "gateway"]
      - XBNET_PROTO=tap                 # ["tap" | "tun"]
  

• This can also be run using the docker run cmd shown below.

  docker run -d --name xbnet_node \
      --privileged \
      -e XBEE_INDEX=1 \
      -e XBEE_BAUDRATE=230400 \
      -e XBEE_PORT=/dev/ttyUSB0 \
      -e XBNET_BASE_SUBNET=2.2.2 \
      -e XBNET_INTERFACE_TYPE=router \
      -e XBNET_PROTO=tap \
      xbnet_node bash /entrypoint.sh
  

3. To run a single xbnet node in DEVELOPEMENT mode, use the following cmd:

• Router mode: sh ./run-single.sh --subnet=7.7.7 --serial-speed=230400 --port=/dev/ttyUSB0 --interface-type=router
• Gateway mode: sh ./run-single.sh --subnet=7.7.7 --serial-speed=230400 --port=/dev/ttyUSB0 --interface-type=gateway

OR Manually build and Start the Docker Container

NOTE: This will require the config .env to be manually modified, based on user needs.

• Configure a single xbnet net service using:

  # Configuration for xbnet0
  XBEE_PORT=/dev/ttyUSB0
  XBEE_BAUDRATE=230400
  XBEE_NET_SRC_IP=192.168.1.100   # Ensure this IP matches the network range
  XBEE_NET_IFACE_NAME=xbnet0
  
  # Default Gateway
  DEFAULT_GATEWAY=192.168.1.1
  

4. To run a multiple xbnet nodes in DEVELOPEMENT mode, use the following cmd:

• Router 1: sh ./run-multiple.sh --index=1 --subnet=7.7.7 --serial-speed=230400 --port=/dev/ttyUSB0 --interface-type=router
• Router 2: sh ./run-multiple.sh --index=2 --subnet=7.7.7 --serial-speed=230400 --port=/dev/ttyUSB0 --interface-type=router
• Gateway: sh ./run-multiple.sh --subnet=7.7.7 --serial-speed=230400 --port=/dev/ttyUSB0 --interface-type=gateway

NOTE: This will require the config .env to be manually modified, based on user needs.

• Configure multiple xbnet net services using:

  # Configuration for xbnet0 (REQUIRED: minimum config to run a single xbnet node)
  XBEE0_PORT=/dev/ttyUSB0               # The serial port for the XBee device
  XBEE0_BAUDRATE=230400                 # Baud rate for the XBee device
  XBEE0_NET_SRC_IP=192.168.1.100        # Source IP for the XBee network
  XBEE0_NET_IFACE_NAME=xbnet0           # Interface name for the XBee network
  
  # Configuration for xbnet1 (OPTIONAL: only required for multi node xbnets)
  XBEE1_PORT=/dev/ttyUSB1
  XBEE1_BAUDRATE=230400
  XBEE1_NET_SRC_IP=192.168.1.101
  XBEE1_NET_IFACE_NAME=xbnet1
  
  # Default Gateway (REQUIRED: part of minimum concifg to run a single xbnet node)
  DEFAULT_GATEWAY=192.168.1.1
  

This will build the Docker image and start the container with the XBee network and the required setup.

5. Health Check and Container Management

The container includes a health check that pings the XBee network interface to ensure it is functioning properly.
The container is configured to restart automatically if the health check fails.

6. Troubleshooting

Ensure the XBee devices are connected to the correct serial ports.
Verify the network interfaces using ip a inside the container.
The container logs can be viewed using:

docker logs xbee_node
